  • Patent number: 6222573
    Abstract: In a heat transfer recording apparatus for printing on photographic print paper using an ink film coated with sublimable ink, density unevenness that occurs at the edges of the wide printing paper is prevented by compensating density in the area that corresponds to the difference between wide print paper and narrow print paper.
    Type: Grant
    Filed: August 5, 1998
    Date of Patent: April 24, 2001
    Assignee: Minolta Co., Ltd.
    Inventors: Takashi Shibuki, Takeo Katsuda
  • Patent number: 6186683
    Abstract: In a heat transfer recording apparatus for printing images on recording paper by bringing ink film in contact with recording paper and heating them by means of a thermal head, the preheating time of the thermal head is decided based on the thermal head temperature detected by a thermistor and the accumulated power supply time obtained as a product of the number of times power is supplied to the thermal head and the detection interval, thus to achieve a uniform image quality by eliminating the effect of the thermal head heat accumulation even in case of forming multiple images successively on multiple sheets of recording paper.

  • Patent number: 6133930
    Abstract: A thermal transfer recording apparatus for thermally transferring a film of a transparent resin as a top coat layer to an image formed surface of a recording paper, includes a thermal head which generates heat in proportion to a supplied energy, and a control unit to keep the supplied energy under control such that the energy supplied during an application of film to an initial area of recording paper extending a length from the starting position of an application of the supplied energy, is greater than a supplied energy during an application of film to remaining areas of the recording paper. The apparatus promptly obtains the temperature appropriate for the transfer of film and faultlessly transfers the film to the recording paper, including an initial printing area of such recording paper.
